--- Comment #3 from Daniel Krügler <daniel.kruegler at googlemail dot com> --- (In reply to Jonathan Wakely from comment #2) > trunk/gcc/testsuite/g++.dg/cpp1y/feat-neg.C Thanks for your work on that Jonathan! Just out of curiosity: All tests within feat-neg.C seem counter-intuitive to me, because it seems that the idea of that test is that everything within is supposed to fail on success - is that intended?
